GAIN
Adjust the gain
for the light
conditions.
Using the Filter With the Collimator
Light sources from a much more directed area can be
detected using the filter with the included collimator. See
Figure 3.
Adjusting the Gain Setting for Varying Light
Conditions
Select the appropriate gain setting on the sensor box for
the light levels to be measured (Figure 4). The correct
gain setting is the one for which the intensity levels on the
display vary appropriately for measuring the relative light
intensity changes in your experiment.

Mounting on an Experimental Apparatus
Use the 1/4-20 threaded connector located on the bottom
of the sensor box to secure the Pressure Sensor to an
experimental apparatus (Figure 5). The alignment hole
fits over an alignment pin included on some PASCO
apparatuses.
